Calculator guide
Understanding Email Campaign Performance Calculator
Evaluate an email send from delivery through unique opens, unique clicks, purchases, revenue, and gross profit while keeping unsubscribes and spam complaints visible. Delivery and list-health measures are not hidden inside a generic conversion funnel.
Detailed calculation process
Reconcile email delivery, engagement, purchases, and list health
The default sends 120,000 emails at 97.5% delivery, 34% unique open, 3.8% unique click, 5.5% click purchase, $140 AOV, 64% gross margin, and $8,500 campaign cost.
General formula: Delivered = Sent d/100Bounced = Sent - DeliveredOpens = Delivered o/100Clicks = Delivered c/100Purchases = Clicks p/100Revenue = Purchases AOVGP = Revenue g/100Profit = GP - CostCTOR = Clicks/OpenUnsubs = Delivered u/100Complaints = Delivered q/100 Delivery establishes the eligible audience. Opens and clicks are separate percentages of that audience, purchases are a percentage of unique clicks, and list-health counts use delivered mail.

Worked situations
Practical examples
- A 97.5% delivery rate on 120,000 sent emails produces 117,000 delivered and 3,000 bounced messages.
- A 3.8% unique click rate creates 4,446 clickers; at 5.5% purchase rate they generate 244.53 expected purchases.
Better inputs
Useful tips
- Use delivered messages rather than sent messages when calculating rates affected by bounces.
- Keep unique clicks and unique conversions separate from total event counts generated by repeat activity.
- Review unsubscribes, complaints, deliverability, and holdout lift alongside the calculated campaign contribution.
Before relying on the result
Limitations and common mistakes
- Opens may include machine activity and are not a reliable measure for every mailbox provider.
- The model does not value future revenue lost through unsubscribes or reputation damage.
- Attribution, refunds, repeat purchases, coupon leakage, taxes, and incremental lift are excluded.
Reference
Key terms
- Delivery rate
- Share of sent emails accepted as delivered rather than recorded as bounces.
- Click-to-open rate
- Unique clicks divided by unique opens.
- Complaint rate
- Estimated spam complaints divided by delivered messages.
Important note
A profitable send can still damage the list; review complaint and unsubscribe trends before increasing frequency.
Frequently asked questions
Why is open rate not used to calculate clicks?
The entered unique click rate is defined against delivered mail, so applying it to opens would change its denominator.
Can purchases be fractional?
Yes in a rate-based forecast; actual observed campaign purchases are whole counts.
What is the break-even click purchase rate?
It is the 95 break-even purchases divided by 4,446 unique clicks, or about 2.14%.
Does campaign profit value lost subscribers?
No. List attrition and deliverability reputation need a longer-horizon model.
